Hello! I've been using a Razer Orochi mouse for the past two years, and in many ways the experience was hugely disappointing. As an architecture student, I spend a lot of time with CAD software (Autocad, Rhino...) and 3D modeling (Cinema 4D, Rhino...), which is why the Magic Mouse was useless for me. The Razer ***mouse has become so unbearably laggy and glitchy that I'm considering buying a replacement. It would be nice if it were a BT mouse (no annoying dongles in my macbook), with at least a few additional programmable buttons to trigger MacOS gestures. The new Logitech MX Master looks promising, but it's a bit pricy. Do you guys have any other suggestions? Thanks!
